Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| B6201 | 68.5% | 7.09% | -6 min | 18.9% | 621 |
| JetBlue on BUF → JFK | 76.3% | 4.04% | -8 min | 11.1% | 4,259 |
| All BUF → JFK flights | 78.7% | 3.97% | -9 min | 9.7% | 6,380 |
B6201 has cancelled 7.09% of its scheduled departures (44 of 621), against 3.97% for all BUF → JFK flights — this specific departure cancels 3.1 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about B6201 specifically, not about the route it flies.
18.9% of B6201’s arrivals were an hour or more late, against 9.7% across BUF → JFK, so the long delays are more common on this number than on the route.

Why B6201 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies B6201 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6201 pushed back an average of 68 minutes late; when it came in on time or early, an average of 1 minute late.
Matched by tail number to the aircraft’s previous flight into BUF: 567 of 577 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| B6201 | 41% | 61% | 10% |
| Network, same turn | 18% | 85% | 10% |
55 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often B6201’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B6201 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves BUF late, does that still matter by the time it reaches JFK?
B6201 pushes back an average of 28.6 minutes late and reaches the gate at JFK an average of 24.6 minutes late. The 4.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. Its 13.2 minutes on the taxiways at BUF is about what any departure from the airport in that hour spends.
On arrival at JFK, B6201 spends 10.5 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.0 minutes shorter than a typical JFK arrival (11.5 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 4,232 BUF departures. Taxi-in is landing to gate, set against 360,684 arrivals at JFK. More on taxi time.

The hour it leaves BUF
B6201 has one departure time, 7:36 PM, so this is what that hour at BUF is worth.
On-time arrival rate. 4,232 departures from BUF are scheduled in the 7 PM–8 PM hour over the period, against 67,459 across the whole day.
B6201 is scheduled out of BUF at 7:36 PM, in the 7 PM–8 PM bank. Departures from BUF in that hour arrive on time 69.6% of the time against 79.2% across the airport’s whole day — the slot alone is worth 9.7 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from BUF, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
103 min late
against a median of 6 min early
B6201 has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 109 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.
